To all'vwhom it may concern.'

'Be 1t known that I, WILLIAM P. QUEN- TELL, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new anduseful Improvements in Calculating- Machines7 of which the following is a specif along line y--y, Fig. 2. y i yvatio'n of paper rollers.

' v'ation of ratchetand'pawl'mechanism, part fication.

' This inventionrelates to 'certain details of construction the nature and object of which isset forth in the following specification and l claimsand illustrated in the annexed drawof the'frame being cut off. Fig. 7 is a view lillustrating lthe partsy shown by Fig. 6 in a Fig. `8 is a section along dierent position.

Fig. 9 shows the arts line z-z, Fig. 6.

. illustrated by Fig. 8 in a different position.

' sectionalv elevation of Fig.` 10 shows mechanism for actuating a pawl stop. Fig. 11 shows a pawl stop in detail. Fig. 12 shows an inverted plan view of ratchet and pawl mechanism. Fig. 13 is a art of the mechanism and showing the drivellever as having moved the pawl lock .to Vactive position. Fig. 14 is a erspective view of the awl carrier with ad- ]acent arts, such as coil spring and driving pin wit link. y

In this drawing is shown a frame a and keys b normally held raised by s rings c above bars d'. 'These barsl slidean swivel. Several bars with respective rows of keys are shown but the explanation of one sets forth the operation ofthe machine. A spring e Fig. 1.2 coiled about the bar tends to normally hold or swivel the bar so that its cut or shoulder part f Figs. 6 and 7 engages a detent bar fixed to the-frame. The bar is thus held against sliding or longitudinal movement. When thebar is tilted Figs. 7 and 9 to clear itself from the detent g the spring h slides the bar backward. The stud or studs i on the bar has also been moved by the tilt of such bar so that this stud is arrested-in a cut k forming -a shoulder or stop part in the key.

Y Specification of Letters Patent. Application filed April 26, 1907. Serial No. 370,492.

Patented May 19, 1908.

As the stud i engages the stop k the slide of the bar is arrested and the key also is held in depressed position for the time being. As vthe. studs i are placed at diiferent distances from their respective keys the bar has a different extent of slide or longitudinal movement as one key or another is depressed. The return or forward slide Vof the bar is effected by-a drive lever m fulcrumed at n. This fulcrum axle n has arms o one for each bar d. A spring p normally raises or returns the drive lever.` As a bar is returned or slid forward such bar swings a pawl carrier or arm g which has a block or bearing point r Fig. 12 where theV front end of the bar is swivelingly supported. The torsional spring e connected at one end to the bar is braced at the other to this bearing block fr., The rear end of the bar swivels and slides in the frame I or a suitable part of the machine. The bar recedes or is pulled back by spring h which draws back the pawl carrier g and the pawl s. The return or forward movement causes the pawl to move the ratchet 2 one or more ste s as called for. The ratchet connects with tFe computing mechanism hereinafter referred to. The return or forward slide of the bar, l

also frees the depressed key so that the latter rises to its level or elevated position for further operations.l

The pawl carrier g has a loose connection such as in and slot with a pawl lock or mutilated isk. The in of the connection is shown at 3 and the isk at 4. This lock 4 as -`also the pawl carrying arm q and the ratchet 2 are mounted on the common center or axle 5. After the bar has moved the lock disk 4 a certain distance forward to lock'position with pin 6 then the carrying arm q 1s moved by the connection at 3 and thus causes the ratchet 2 to be moved by the pawl s.` The pawl is thus locked to the ratchet and the latter cannot move after the pawl is arrested. Any inaccuracy by the ratchet jumping or moving after the pawl is arrested is thus prevented. Rapid operation can thus' take place without a'ecting the accurate or cleancut rotation of the computing mechanism.

The detent pawl 7 is familiar in ratchet mechanism or the like. The retracting spring h above referred to is connected'to this lock disk 4 and on the return the spring h first retracts the lock 4 and this lock by connection 3 draws back pawl arm q and bar d. The spring h need not be directly connected to the lock 4 but is shown connected to a driving pin link 40 having a pin 41 against which strikes the driving arm o and its spring 12. The ratchets 2 by suitable gears or pinions actuate the numbered disks or register wheels 8 arranged in the usual way for units, tens, and so on. In the construction shown the numbered wheelsk consist eachr of a pinion sleeve 46 and the disk 8 carrying the pin 18. The invention is not limited to such construction however as the pin 18 could be made to protrude directly from the sleeve 46. All such modifications are included in the expression numbered wheels. .When a numbered disk for exam le the unit disk starting from zero has reac ed nine, the next actuation of a key for said disk will have to show a total of ten or more. In other wordsv when the unit-'Wheel is rotated. past nine the ten Wheel must be actuated. This carry over from one column to another is obtained as follows: A pawl detent 9 is pivoted at 10. This pawl detent has a step or cut away-part in its under face as indicated in Fig. 1 1 at the part 11. One such movable detent 9 is arranged for each numbered Wheel or column except the unit column the pawl of which is arrested by a fixed detent or fixed part of the frame Without cut away portion. Ordinarily the pawl s is arrested by the full part of the movable detent but when the cut or step part is in line with the pawl the latter can move one more figure which is the carry over from the column to the right. The pressure` for giving the additional move or step is iven by spring 12 on each arm o of the drive iever. As such drive lever is swung the spring 12 is compressed against the bar d or a suitable stop or stud 41 on said bar so as to cause the 'awl to move into the step 11 when the latter 1s in line with the pawl. This pawl detent is engaged by an arm of lever 13 fulcrumed on bar 14. The other arm of this lever has a stud 15 and a third arm of this lever is shown at 16. The fulcrums 10 and 14 are at an angle to one another and the fulcrum 10 is supported in the bar or fulcrum 14 and in a bar 17 parallel to bar 14.

On the numbered wheel 8 is astud 18 and at a suitable time this stud 18 strikes stud 15 and swings-lever 13 to set the detent 9 with its step 1 1 in line with the pawl. The return of the detent is effected by the bail 19 engaging arm 16 and swinging the lever and at-20 and is connected to a link 21 supported detent back. The bail 19 Fig. 6 is fulcrumed at 22 by swinging arm 23. The pins 22 project into the paths of arms 24 on a fulcrum bar n. A s the drive lever m returns or rises the respective arm 24 swings bail 19 and arm 16 to reset the detent 9. y The drive lever or an arm 24 thereof also actuates a bar 25 Fig. 2 which is returned or slid back by spring 26. This reciprocating or slide bar actuates a lever 27 with hammer head 28 and also a lever erally the gear Wheels cause the other roller to be likewise set. The spindles 36 of the paper rollers or one of the spindles has shoulders or dents 37 along its length and a pawl 38 on the sleeve or rollers engaging such dents prevents accideninl shift of the paper rollers. The carriage or support of the shafts 36 is fixed or does not move laterally.

The operation of the device is readily understood. As a key b guided b or sliding on cross rods 39 is depressed the ar d is tilted to free itself from the detent blade or fixed bar g and its spring 7L then slides or snaps the bar for lstud i to lock the stem of key bwhich is now held depressed. At the same time the pawl s is retracted the desired distance. After the desired keys have been actuated the drive lever m is moved and such lever sliding the bars d' forward releases the ke s which again rise to the former level. At t e same time the pawl mechanism actuates the numbered wheel or wheels and the arm 24 of lever m moves the connection 25 and the receding bar d has set its type line or-bar 35. The total is shown at the sight line of wheels 8 and can be transferred to the paper of rollers 31 by the operator Writing the separate figures showing the total.

On bar 25 is a cam face 42 Fig. 2 which engages a trip 43 on lever arm 27. This cam and trip 43 will actuate arm 27 when the bar moves forward, but on the return of the bar the trip 43 will yield and the arm 27 remains stationary. After `the desired keys are set the lever mis depressed andthrough its arm 24 it draws forward bar25 which by cam face 42 and arm 27 brings the hammer 28 to strike the type 33 to the paper. Further depression of lever m moves the cam 42 ast the arm 27 liberating the'hammer 28 w ich is returned by the spring 44. The lever m also by further movement brings arm o with its spring 12 to bear on pin 41 and thus conveys motion to the ratchet mechanism and numbered wheels 8. Byhaving rollers 3.1. slidable on their shafts which latter are mounted on fixed bearings the paper can be shifted in relation to the printing mechanism so that more than one column can be added on the sheet Without it being necessary to move the carriage laterally. The slide bar 25 actuates lever` 29 with pawl 30` engaging a ratchet 45 on one of the shafts 36.
